yeah basically ive got a 16" rim with 225/40/zr16 these tyres are for 150 mph and over i do not need these on this rim im sure you would agree so im wondering what is the smallest tyre im going to get on the rim without it looking daft safe etc cause i like the rims and i dont wanna get rid of them also mot is coming up and with them rubbing on the inside of the wheel arches there going to laugh at me, although i have thought about spacers but unsure on size as i dont want to take the spigot rings out of place to much. cheers
